Given a saturated solution of CaF2, write the ionic equilibrium and use it to calculate the solubility of CaF2.

My answer for the ionic equation is
CaF2(s)<->Ca2+(aq)+ 2F-(aq)
Ksp= [Ca2+][F-]2

the given ksp is 3.32*10-4

how do i figure out the solubility??
i know the stoichiometry is 1:2 but i don't know how to finish this problem... please help
